Combining Price Amplitude, Convertible Bond Data, and KDJ Momentum

Summary

The document proposes a Chinese stock screen combining price movement, convertible bond information, and the KDJ indicator. Its stated idea is to select shares with amplitude above a threshold, a nonempty name for an outstanding convertible bond, and a rising K value. It presents these as volatility, financing, and technical signals, respectively, and notes that KDJ can lag and that relying heavily on indicators may overlook fundamentals and broader market conditions.

The article includes formula and Python examples, but their conditions do not align cleanly with the stated screen. The formula uses a close-to-prior-close return threshold and a KDJ/MACD expression, while the Python example checks the open-to-close change and an increase in K; its shown data queries do not clearly implement the convertible bond condition. No backtest results or evidence of predictive performance are reported. The screen should therefore be treated as an idea requiring data and logic verification, with additional fundamental checks and testing suggested by the article.

Key ideas

• The proposed screen combines price movement, convertible bond naming data, and KDJ K-line growth.
• The article links these inputs to volatility, financing context, and technical momentum.
• It warns that KDJ can lag and that indicator-only selection may miss fundamental or market risks.
• The formula and Python examples implement differing conditions, so the screening logic needs verification.
• No backtest results are provided to establish the strategy’s performance.
